ppc440spe_d...01pqzero_sum(9)

Okay bestie, welcome to the Kernel API Manual page for ppc440spe_d...01pqzero_sum(9) — yes, the title is a whole keyboard smash and we’re moving with it. 💅

💅 NAME

ppc440spe_desc_init_dma01pqzero_sum — initialize the descriptor for PQ_ZERO_SUM operation. That’s literally the whole NAME section, and it ate. ✨

✨ SYNOPSIS

Here’s the exact function signature, untouched and iconic:

void ppc440spe_desc_init_dma01pqzero_sum (struct
       ppc440spe_adma_desc_slot *desc , int dst_cnt , int src_cnt );

🎀 ARGUMENTS

Okay so the manual is not giving us anything here — every single argument is listed as -- undescribed --. No cap, that’s genuinely all it says:

• desc — -- undescribed --. The manual left this one mysterious, bestie. 😭
• dst_cnt — -- undescribed --. Also a mystery; I’m not making up lore. 🙈
• src_cnt — -- undescribed --. Same energy, same blank spot. 💀
